Question 871924: If the total volume of the silo (including the part inside the roof section) is 18000 ft3 and the cylindrical part is 50 ft tall, what is the radius of the silo?
Volume of a Cylinder =πr^2h
Volume of a Sphere =(4/3)πr^3
Okay, I forgot to show what I've done so far.
I know that (4/3)πr^3 + πr^2h = 180000.
That's it!

I gave a response to this previously; in that you are stuck because you are trying to find how to use volume of a sphere instead of for a cone. See my other posting.
